Antenna Selection - HELP!

First - Thanks for taking time to answer!

We have a ~30 y/old 'Wiengard' full size (analog) type antenna mounted in the attic. The signal strength is on-the-edge with pixelation/signal-loss happening frequently with any weather change.

Please advise on suggested types of antenna(s), rotator, amplifier, etc. Also, any recommendations on cable-brands, balun/connector types & brands, would be welcome.

Thanks again,
Dennis

Antenna Selection HELP!

First -- Thank You for assisting!

I want to upgrade an existing antenna (~30 y/o weingard-type analog) that is placed in the attic. I will likely place the new antenna in the attic as well.

The TV signals are often pixelated with weather changes, and more and more station-signals are becoming too weak to display.

The height is approx 20+', the current antenna is connected to a 'converter' box ... to an analog tuner TV. What antenna types/brands, rotators, signal amps, connectors, etc. would give an optimal signal in this setting?

Thanks Again,
Dennis

If the signal from KGO, (broadcast on VHF CH-7) is strong and stable, I suspect the old antenna is a VHF only design. Unless it's damaged it would be useful and could continue in service, receiving VHF signals.

A UHF antenna is needed to reliably receive the majority of the available signals. Any of the 4-bay panel antennas would be a good choice. (U4000, DB-4, CS4, DB4e, CM4221 and HD4400) I would aim toward the NE (Sutro Tower)

You would need a UVSJ to combine the signals from the VHF antenna with the UHF.

Connecting a few tuners should not require any amplifier.

If it turns out that your attic is a poor location for an antenna, (wet roofing attenuates and reflects more than dry, tile and metal are also unfriendly to TV & radio signals). A small RCA ANT-751 mounted outside would be an option. It has both UHF and VHF capability.

If the well is dry and you don't see rain on the horizon, you'll need to dig the hole deeper. (If the antenna can't get the job done, an amp won't fix it.)

Reception

I recommend a one antenna solution , a Winegard HD7000R antenna aimed at about 350 degree magnetic compass. Here is how to aim antennas , http://www.kyes.com/pointing/pointing.html. Mount the antenna above the roof with one of these antenna mounts. http://www.ronard.com/909911.html , http://www.ronard.com/34424560.html , http://www.ronard.com/ychim.html. . The long rods at back of the antenna will help block multipath , ( reflected signals ) that are a real problem at your location between the mountains. Reflected signal interfer with a tv tuners ability to tune in channels. Here are some places to buy antennas and etc. , http://winegarddirect.com , http://www.solidsignal.com , http://www.amazon.com
